React Native & Expo Development
Cross-platform React Native apps with Expo — one codebase, two stores, fast iteration.

01 What it is
What this service is
React Native is a framework for building native iOS and Android apps from a single JavaScript / TypeScript codebase. Expo is the supporting toolchain that makes React Native genuinely productive — managed builds via EAS, OTA updates via Updates, Expo Router for navigation, and a curated set of native modules.
At devinsta we ship React Native apps using Expo Router (file-based navigation), TypeScript, EAS Build for CI/CD, and EAS Updates for over-the-air updates.
02 What it's for
What it's for
React Native earns its keep when feature parity across iOS and Android matters, the team has React expertise, and the use case doesn't need niche native APIs that would force constant ejection. Typical fit: B2C consumer apps, content apps, productivity tools, internal tools, and field tooling.
It's less ideal for games, AR-heavy apps, or apps that need deep platform integration that the React Native ecosystem doesn't cover well.
03 How to use it
How to engage devinsta
MVPs run 8–14 weeks for both iOS and Android — typically 30–40% faster than building two native apps. We ship preview builds via EAS Update from week two, internal beta via TestFlight + Play Internal from week six, and dual store submission at the end.
04 How to deploy
How we deploy it
Builds run on EAS Build with CI gates. We use EAS Updates for OTA fixes (subject to App Store / Play Store guidelines), Sentry for crash reporting, and a structured release process: a feature flag for every risky change, a staged rollout for every binary release, and a documented rollback path.

FAQ
Common questions
Will it look native?
Yes — React Native renders native UI components. Done well, a React Native app is indistinguishable from a fully native one for the vast majority of users. We pay close attention to platform-idiomatic details (iOS-style headers vs Material headers, haptics, animations) so each platform feels native.
What about OTA updates and App Store rules?
OTA updates are allowed for non-binary changes (JS bundle, assets). They cannot change app behaviour fundamentally per Apple's guidelines. We use EAS Updates with a clear policy of what qualifies for OTA vs a full re-submission.
Can you handle native modules?
Yes — we write Expo Modules (the modern way) or fall back to bare React Native when a niche native capability is required. We avoid ejecting from Expo's managed workflow unless absolutely necessary.
